Here's what happened: I had saw a mod's signature and l decided to leave and come back a little while later, but the signature had a different picture on it! But this was no coincidence: I tried quickly refreshing the page and the signature picture was different everytime!

I saw that this happens on Serpentsound's sig and Darkend's sig (and maybe a few other Mod's signatures).

So here's the question: how do you make your signature automaticly change like that??? Is it just a moderator thing or what?
